Register configuration synchronization method, verification platform system, configuration method and device

Abstract

The invention provides a register configuration synchronization method, a verification platform system and a configuration method and device, and the register configuration synchronization method comprises the steps of configuring a register of a register model according to register configuration information when the register model in a CPP form receives the register configuration information; andtransmitting the register configuration information to the BFM in the SV environment through the DPI so as to send the register configuration information to the DUT through the BFM and further configure the register of the DUT. Thus, register configuration in the CPP environment and the SV environment can be achieved at the same time only by inputting register configuration information into the register model in the CPP form, the problem that register configuration needs to be conducted on the two sides of a reg model (SV) and a reg model (CPP) respectively in an existing configuration schemeis solved, and the configuration workload of a register is effectively reduced.

Description

technical field [0001] The present application relates to the technical field of integrated circuit verification, and in particular, to a register configuration synchronization method, a verification platform system, a configuration method, and a device. Background technique [0002] As the scale of integrated circuits continues to increase, IC (Integrated Circuit, integrated circuit) verification has also become an extremely complicated task. In practical applications, sometimes in order to speed up the project progress, a series of CPP classes (C plus plus class, C++ class) constitutes the CPP env (C plus plusenvironment, the verification environment for C++ language development) of the verification environment, and then hangs the monitor (monitor) component outside the DUT (design under test, design to be tested), and will observe The received content is directly sent to the CPP env through DPI (direct program interface, direct programming interface) for prediction and c...

AI Technical Summary

Problems solved by technology

[0005] In the above verification process, there are the following two problems: 1. After configuring the registers of the DUT through the reg model (SV), it is also necessary to configure the same content for the reg model (CPP). If there are many registers, there will be Very large and repetitive workload; 2. For a well-developed project, if you want to change some registers later, you need to modify the codes on both sides at the same time, which is very difficult to maintain, and for those who are not familiar with it, you may only configure one On the side, the DUT result is different from the C model prediction result, and it takes a lot of time to debug later errors, which seriously reduces work efficiency
